Siri promo video (Woman asks for weather)

Improved Siri voice is reportedly among the under-the-hood improvements in Apple’s upcoming iOS 8.3 software update. Though a better-sounding Siri may not always be apparent to an untrained ear, Apple should be credited for consistently improving the voice assistant’s speech synthesis capabilities.

Quick comparison of today’s more natural-sounding Siri versus the original Siri from 2011 gives you a good indication of Apple’s advances in this area.

And now with iOS 8.3 in tow, Apple’s bound to boost Siri’s speech synthesis further. Listen to the new and improved Siri voice in iOS 8.3 relative to iOS 8.1.1 and let us know what you think.

The more natural sounding speech synthesis in iOS 8.3 is particularly noticeable on the words “potato” and “America,” as heard in the comparison video below.

The iOS 8.1.1 version comes first, then followed by the improved iOS 8.3.

The Siri voice in iOS 8.3 does sound more confident.

On the other hand, I’m not so sure that’s the result of a vastly improved speech synthesizer in iOS 8.3. If you listen intently, you’ll notice that simply dropping the pitch at the end of certain words does the trick.

Thoughts?

    Not any massive change, but speech is such a tedious and intricate thing. These tiny changes make it much more pleasant.

      I wish more people understood this. The mechanics of human speech -biologically and culturally speaking – are far more complex than we realize. Whereas the way we pronounce and inflect our speech comes out of a lifetime of experience on top of biological functions, a computer can only do so by calling on a large bank of sampled sounds that get cobbled together to form intelligible words. While the way it synthesizes speech can improve with technology, it’s simply not going to come close to what we are capable of.

      That’s why small changes like this make more of a difference than we think. Speech synthesis is a heck of a process.

    It’s always bothered me how she pronounces “shuffled” as “shuf-field”

    • YES! THIS! I can’t believe they still haven’t fixed that!

    The consonant is little different in two words Chris mentioned!

  • James G

    Just changing some inflection points in speech. Seems like an improvement.

  • Sounds less like a computer voice, that’s good!

  • Guest

    sounds good

  • Bugs Bunnay

    Sounds a little more huskier.

    For me the 1-st part looks smoother (2nd part of the sentence) with 8.3 the 1st part sounds better. 🙂

    Only a very subtle change. Unfortunately still behind Google Map’s voice and Cortana. I’m surprised it’s taking Apple this long to improve her voice.

      exactly

    Guys, Siri has sounded like that for a least for a week for me. She says a lot of stuff different like “ready to send it?” more calm and smoother than before. And the funny thing is that it’s NOT 8.3 beta that’s changing her voice. It’s still in 8.1.3.

  • iPhoneWINS

    still sounds like a damn robot from 1982

  • iamzaidan

    Till 8.1.1, siri talks im seperate words like random recorded words being played one after the other
    But in 8.3, that’s hard to tell
